| * iscsi-target; Allow an extra tag_num / 2 number of percpu_ida tagsNicholas Bellinger2013-10-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch bumps the default number of tags allocated per session by iscsi-target via transport_alloc_session_tags() -> percpu_ida_init() by another (tag_num / 2). This is done to take into account the tags waiting to be acknowledged and released in iscsit_ack_from_expstatsn(), but who's number are not directly limited by the CmdSN Window queue_depth being enforced by the target. Using a larger value here is also useful to prevent percpu_ida_alloc() from having to steal tags from other CPUs when no tags are available on the local CPU, while waiting for unacknowledged tags to be released.

| * iscsi-target: Perform release of acknowledged tags from RX contextNicholas Bellinger2013-10-031-4/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch converts iscsit_ack_from_expstatsn() to populate a local ack_list of commands, and call iscsit_free_cmd() directly from RX thread context, instead of using iscsit_add_cmd_to_immediate_queue() to queue the acknowledged commands to be released from TX thread context. It is helpful to release the acknowledge commands as quickly as possible, along with the associated percpu_ida tags, in order to prevent percpu_ida_alloc() from having to steal tags from other CPUs while waiting for iscsit_free_cmd() to happen from TX thread context.

| * iscsi-target: Only perform wait_for_tasks when performing shutdownNicholas Bellinger2013-10-031-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | This patch changes transport_generic_free_cmd() to only wait_for_tasks when shutdown=true is passed to iscsit_free_cmd(). With the advent of >= v3.10 iscsi-target code using se_cmd->cmd_kref, the extra wait_for_tasks with shutdown=false is unnecessary, and may end up causing an extra context switch when releasing WRITEs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch addresses a bug for backends such as IBLOCK that perform asynchronous completion via transport_complete_cmd(), that will call target_complete_failure_work() -> transport_generic_request_failure(), upon exception status and invoke cmd->transport_complete_callback() -> compare_and_write_callback() incorrectly during the failure case. It adds a check for a non zero se_cmd->scsi_status within the first invocation of compare_and_write_callback(), and will jump to out plus up se_device->caw_sem before exiting the callback.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch addresses a bug when compare_and_write_callback() invoked from target_complete_ok_work() hits an failure from __target_execute_cmd() -> cmd->execute_cmd(), that ends up calling transport_generic_request_failure() -> compare_and_write_post(), thus causing SCF_COMPARE_AND_WRITE_POST to incorrectly be set. The result of this bug is that target_complete_ok_work() no longer hits the if (!rc && !(cmd->se_cmd_flags & SCF_COMPARE_AND_WRITE_POST) check that forces an immediate return, and instead double completes the se_cmd in question, triggering an OOPs in the process. This patch changes compare_and_write_post() to only set this bit when a failure has not already occured to ensure the immediate return from within target_complete_ok_work(), and thus allow transport_generic_request_failure() to handle the sending of the CHECK_CONDITION exception status.

This is done late enough in sbc_compare_and_write() after the memory allocations have occured in transport_generic_new_cmd() to not cause any unwanted side-effects.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a bug where ib_destroy_cm_id() was incorrectly being called after srpt_destroy_ch_ib() had destroyed the active QP. This would result in the following failed SRP_LOGIN_REQ messages: Received SRP_LOGIN_REQ with i_port_id 0x0:0x2590ffff1762bd, t_port_id 0x2c903009f8f40:0x2c903009f8f40 and it_iu_len 260 on port 1 (guid=0xfe80000000000000:0x2c903009f8f41) Received SRP_LOGIN_REQ with i_port_id 0x0:0x2590ffff1758f9, t_port_id 0x2c903009f8f40:0x2c903009f8f40 and it_iu_len 260 on port 2 (guid=0xfe80000000000000:0x2c903009f8f42) Received SRP_LOGIN_REQ with i_port_id 0x0:0x2590ffff175941, t_port_id 0x2c903009f8f40:0x2c903009f8f40 and it_iu_len 260 on port 2 (guid=0xfe80000000000000:0x2c90300a3cfb2) Received SRP_LOGIN_REQ with i_port_id 0x0:0x2590ffff176299, t_port_id 0x2c903009f8f40:0x2c903009f8f40 and it_iu_len 260 on port 1 (guid=0xfe80000000000000:0x2c90300a3cfb1) mlx4_core 0000:84:00.0: command 0x19 failed: fw status = 0x9 rejected SRP_LOGIN_REQ because creating a new RDMA channel failed.
